T0 aZZ whom, it may concern:

Be it known that we, HENRI GALOPIN,'a citizen of the Republic of France, residing at Melbourne, in the British Colony of Victoria, and JAMES EVANS, a subject of the Queen of Great Britain, residing at Burwood Road, Auburn, in the said Colony of Victoria, have invented an Improved Incandescent Burnerfor Burning Atmospheric Air Charged with I-Iydrocarbon Vapors, (for which letters Patent have been grantedin Victoria, No. 4,182, dated August 17, 1885; in South Australia, No. 606, dated September 28,1885; in Tasmania, N0. 372, dated September 80, 1885; in New Zealand, No. 1,581, dated October9, 1885; in New South Wales, dated December 2, 1885, unnumbered, and in Queensland, No. 45, dated September 13, 1885,) of which the following is a full, clear, and exact description.

Our invention has been designed for the purpose of obtaining abetterlight than can otherwise be obtained from the combustion of atmospheric air charged with hydrocarbon vapors; and it consists in'apeculiar construction of burner, and in the arrangement of parts connected therewith, substantially as hereinafter described. 7

The invention further consists in means whereby the devices may be made self-lighting, so that by simply turning on the gassupply the gas at the inainburner will be relighted, substantially as hereinafter fully set forth.

Referring to the drawings, Figure 1 is a detached vertical sectional elevatiou'of the incandescent burner, burner-pipe, gas-holder, and gassupply pipe, showingapilot-burnerin said burner-pipe,whereby the device is made self-igniting. Fig. 2 is a detached elevation of the plug of the stop-cock O on an enlarged scale. Fig. 3 is asection on line 00 w of Fig. 2. Fig. at is a vertical section, on an enlarged scale, through the incandescent burner, illustrating the construction of the latter. Fig. 5 shows a portion of the double-wire fabric employed in the construction of the incandescent burner.

In the above drawings, J indicates the gassupply pipe provided with a stop-cook, J

and connected with one end of a gas holder or reservoir,,J, to the other end of which is secured a tapering tube, J", in which are arranged one or more perforated diaphragms or wire-gauze partitions, J toprevent the flame from the burner being communicated to the gas in the reservoir J. In this tube J isiitted a burner-tube, K, that is made tapering outwardly, and carries at its enlarged outer end a burner constructed of a material capable of being brought to incandescence. This burner K- is made of platinum wire-gauze, and preferably of two thicknesses of gauze, 7c is, so arranged that the meshes of the inner layer, It, will intersect those of the outer layer, is, thereby reducing the size of the meshes correspondingly, and consequently the orifices through which the gas would otherwise escape too freely, all as more plainly shown in Figs.4 and 5.

The burner K is constructed in the form of a conical basket, as shown, and forms'in its interior a gas-chamber into which gas from the reservoir J flows, and where it is ignited to bring the basket to a state of incandescence.

By means of the described construction, the gas supplied to reservoir J is highly heated by the heat generated at the burner, said reservoir being in sufficiently close proximity to said burner to effect this preheating, and as the gas reaches the open-work burner in a highly-heated state is there ignited and com bines with atmospheric air to produce an in tense heat that rapidly brings the burner to a state of incandescence, a brilliant light with: out flame being thus obtained.

The described illuminating device may be made self-igniting by applying a pilot-burner, J", to the upper smalt end of the burnertube K, as shown in Fig. 1. In this construction we apply a stop-cock, O, to the pipe J so constructed as to allow, when closed, suificient gas to pass through to keep a light at the pilot-burner without unduly heating the tube, so that when the gas is fully turned on it will not require to be lit. To this end the stop-cock has a peripheral groove extending half around the same from the main pasincandescent properties.

sage thereof, as plainly shown in Figs. 2 and 3. By means of this construction we obtain a selfigniting light, and the operation of the devices is substantially the same as when the pilotbnrner is not employed, except that the gas passing through the burner-tube is further heated by the flame at the pilot-burner, and results in a more thorough or complete combustion, and consequently a more brilliant light. \Vhen it is desired to extinguish the light,whether the pilot-burner is used or not,

the cock J is turned to cut oil the supply of gas to the reservoir J.

We are aware of United States Patent granted to O. Clamond, No. 261,529, under date of July 25, 1882, and also of British Patent No.1,403

of 1882; but the constructions therein shown atively coarse mesh, and reduce thesize of the mesh by the arrangement of twolayers of such fabric, as described; and, lastly, by this arrangementof burner we provide a light-radiating surface nearly twice as great as that obtained by a single layer of fabric.

Having now described our invention, what we claim, and desire to secure by Letters Patent, is-

The herein-described incandescent burner, consisting of the gas-holder J, the tapering pipe J connected therewith and provided with a stop-cock, 0, having a groove formed in one-halfof its perimeter, the ends of which groove merge into the transverse aperture of said stop-cock, and the gauze diaphragms J,

J interposed in pipe J, below the stop-cock O, in combination with the tapering burnerpipe K, carrying at the smaller end within the pipe J a pilot-burner, J, and at its wider end a burner, K, composed of two layers of platinum wire-gauze, the meshes of which intersect one another, substantially as described, for the purpose specified.
